UV Odorless Conformal Coating Fast Curing LED Moisture Thermal Cure for PCB Solar Panel 3100D

Product Overview

UV Odorless Conformal Coating

3100D is an odorless UV conformal coating designed for protective coating of PCB circuit boards, solar panels and other electronic assemblies. It cures fast with selectable LED UV, UV moisture and UV thermal cure systems, provides good adhesion to PCB substrates, plastic, glass and metal, and offers excellent anti-yellowing, moisture and chemical resistance. An optional blue fluorescence version makes coating coverage inspection quick and easy.

Key Features

• Fast curing, selectable cure systems - choose LED UV, UV moisture or UV thermal curing to match your production line; shadow areas can be fully cured by secondary moisture or heat cure
• Odorless formulation - low odor during application and curing for a better working environment
• Broad adhesion - good adhesion to PCB substrates, plastic, glass and metal surfaces
• Optional blue fluorescence - coating coverage is easy to inspect under UV light for quality control
• Excellent anti-yellowing, moisture and chemical resistance - long-term reliable protection of coated assemblies
• Proven electronics protection - suitable for conformal coating of PCB circuit boards, solar panels and more

Technical Specifications

Product Applications

3100D is a versatile conformal coating for moisture, dust and chemical protection of electronic assemblies. Typical applications include:

• PCB circuit board coating - conformal coating protects PCBs from moisture, humidity, dust and chemical contamination in service
• Solar panel protection - protective coating for solar panel circuits and components against environmental exposure
• Electronic assembly coating - suitable for coating assembled boards, modules and sensitive electronic parts
• Shadow-area curing - UV moisture and UV thermal cure options ensure areas hidden from direct UV light are fully cured
• Fluorescence inspection - blue fluorescence version allows fast, reliable coating coverage inspection under UV light
• Multi-substrate coating - good adhesion to PCB substrate, plastic, glass and metal surfaces within one assembly

Frequently Asked Questions

1. What is 3100D mainly used for?
   It is an odorless UV conformal coating used to protect PCB circuit boards, solar panels and electronic assemblies from moisture, dust and chemicals, extending service life and reliability.
2. Which curing options does 3100D support?
